Models of potential species distribution are a tool to visualize the range of suitable habitats where species could occur. The objective was to carry out a review of the distribution of four endemic bird species in a threatened situation, their niches and to design a potential predictive model of the distribution of species in the La Libertad region. The points of presence of Aglaeactis aliciae, Aulacorhynchus huallagae, Scytalopus unicolor y Asthenes dorbignyi huancavelicae, were obtained from the GBIF and eBird database, and the climatic predictors from WorldClim. The potential niche modeling of species and geographic distributions was carried out using maximum entropy algorithms (MaxEnt), in the Wallace platform (V1.0.6.3), around the RStudio program and map design with the QGIS program. The AUC values obtained for the species were A. aliciae 0.915, A. huallagae 0.804, S. unicolor 0.824 and A. dorbignyi huancavalicae 0.904. If the AUC values are = 0.75, they indicate a good performance of the model to discriminate the areas with and without the presence of the species. [ABSTRACT FROM AUTHOR]

The sugarcane crop is cultivated in about 140 000 ha in the Peruvian coastal area. The average yield is 140 t/ha-year and 10-12% sucrose. However, the occurrence of El Niño phenomenon very seriously affects cane quality and production. An investigation was carried out to determine the effect of minimum temperatures, above 18°C, in sugar cane juice quality and in the presence of insects in two sugarcane plantations during El Niño 1982-83 and 1997-98 events. Information was obtained from samples that were collected and processed to determine stem maturation, between September 1982 and February 1983 (Paramonga) and between January 1997 and December 1998 (Casa Grande). It was found out that maturation was seriously affected. In Paramonga, for each temperature unit increase, there was a change in pol percent. In Casa Grande, minimum temperature increases reduced pol percent (R2=0.53). The insect pests Diatraea saccharalis (F.) and Perkinsiella saccharicida showed increases in their populations and produced sugar losses. Increases in Sipha flava, Aphis sacchari and Metamasius hemipterus were also found. Rats (Rattus norvegicus) affected almost 40 percent of stem internodes. [ABSTRACT FROM AUTHOR]

In parks and green areas of the district of Trujillo we can watch diverse birds of wild origin. Before its foundation, Trujillo was a carob forest, a situation that changed with the pass of the years. The obtaining of firewood and coal as an energy source, the change of land use for intensive agriculture and disorganized urbanism were the cause of its destruction, without considering the approach of sustainable cities over time. In order to assess the presence of wild birds associated with the flora and the urban environment, we conducted visits through thirty parks in the district of Trujillo and green areas of some public institutions. Using the method of sampling by points, in each green area, and according to the size, five observation points were defined by park, in which we stayed for 10 minutes, making the auditory and photographic record of the species; and of the flora related to the ornithofauna according to their way of life (herbs, shrubs, vines, climbers and trees). A total of 47 bird species were recorded, as well as 224 species of plants used as ornamentals, including 28 native ones, mainly herbs, shrubs and trees, which in one way or another, the birds find favorable conditions for feeding, resting and nesting. The varied existing flora allows the presence of birds from different communities, constituting a recreational attraction for people; we suggest to promote the planting of native species and their conservation.

We present a new record and eating habits of Phytotoma raimondii Taczanowski, 1883 (Passeriformes: Cotingidae), “Peruvian plantcutter" in Jolluco Alto, Cascas District, Gran Chimu Province, La Libertad Region, between 658 and 674 m of altitude, from April to September 2015. We showed that in addition to young buds of several shrubs that this species uses as alimentary resource, it also feeds on mature fruits of shrubs from the surroundings according to the plant phenological stage. In Jolluco Alto forest, it was verified that it feeds mainly on mature fruits of Vallesia glabra (Cav.) Link (Apocynaceae) “cuncuno". [ABSTRACT FROM AUTHOR]

Food and interspecific competition generates an evolutionary divergence in morphological traits in organisms. Therefore, the objective of the study is to identify the morphometric characteristics of birds that keep positive relationship with the type of food they consume. To do this, capture of birds was conducted in mist nets and birds captured under eleven parameters were measured before performing Principal Component Analysis (PCA) in SPAD-N. Nectarivorous, frugivorous, granivorous and insectivorous: 18 individuals corresponding to 9 species, grouped into four guilds were captured. After relating the Factor 1 with Factor 2, four groups, of which the largest are formed is a mixed group to include granivorous and insectivorous species; the second group includes nectarivorous and insectivorous species; and the third is represented by only frugivorous species. Morphometric characteristics of birds that are most positive relationship with your food guild, are what determine the shape and peak so large and the size of the bird. [ABSTRACT FROM AUTHOR]

El artículo discurre sobre las políticas relacionadas con la traducción al inglés de la literatura latinoamericana, con un enfoque particular en México. La autora comenta sobre la relación entre la literatura y la cultura, y describe algunos de los criterios de la traducción, incluyendo la recepción favorable de la obra.

“El libro vacío” (1958) by novelist Josefina Vicens (1911-1978) is a rare work in the context of Mexican novels of its generation. It has been analyzed primarily as an example of a nascent feminist movement and in relation to existentialism. The present article, however, proposes a rereading establishing the echos that exist between this novel and the work of Maurice Blanchot, in particular “Le livre à venir (El libro por venir) (1959), published a year after Vicen’s novel but which collects essays previously published. Both texts analyze the literary experience as an unfinished process in constant transformation, erasing the border between the book and the literary language. The protagonist of Vincen’s novel, José García, writes in his diary intuitions about the literary act and about a novel that he will never write, but that echoes the ideas of Blanchot. In his notes, as in the essays of the French theorist and narrator, the literary text rises from a language that is articulated as a pure exteriority, following here the work of Michel Foucault. More than fifty years after its publication, tending to the echoes that reverberate in the empty spaces that are central to this important work of Mexican narrative serves to recognize the modernity in Vinces’ text and her progressive passion in the contemporary Latin American tradition.

The article examines the first centennial celebration of the Mexican War of Independence, on September 16, 1910 and the ensuing dictatorship of Porfírio Díaz. The author comments that the celebration ceremonies and attitudes have, since then, always been the same, no matter the country's situation. It is suggested the reading of Efrén Rebolledo's book "Nikko" to reflect and counterbalance the ideology presented on this commemoration and its influence on Mexican's national characteristics.

This article focuses on social movements and conflicts during the period of Latin American independence in the early 19th century, particularly in colonial Guatemala. It examines the drafting of the Guatemalan Constitution in 1812. The author explores the relationship between the government of Nueva Guatemala, the social elite, and the indigenous population. He also analyzes the tensions and conflict that arose between the native Guatemalans and the Spanish population living in colonial Guatemala during this time period.

The article focuses on local political relations between Indian leaders, municipal government and the archbishop of Guatemala in early 19th century Totonicapán, Guatemala. The author discusses the alliance between popular sectors and local government in opposition to the Spanish colonial government. He examines the issues, including the refusal to answer to colonial authorities (in representation of the Spanish Courts of Cadiz) and the protest against the tax requirements, which led to the political alliance between Indian groups, lower class peasants and municipal leaders in Totonicapán. The author also comments on the political role of the Guatemalan Ladino-Spanish elite.

Los autores ofrecen una perspectiva detallada de los correlatos de la ansiedad comórbida en una muestra amplia, bien caracterizada, de pacientes con trastorno bipolar. Método: Se examinaron la ansiedad y sus correlatos en una muestra transversal de los primeros 500 pacientes con trastorno bipolar I o II incluidos en el Systematic Treatment Enhancement Program for Bipolar Disorder, un proyecto multicéntrico financiado por el National Institute of Mental Health, diseñado para evaluar la evolución longitudinal de los pacientes con trastorno bipolar. Resultados: Los trastornos de ansiedad comórbidos a lo largo de la vida fueron frecuentes, ocurrieron en más de la mitad de la muestra y se relacionaron con una menor edad de inicio, una menor probabilidad de recuperación, un peor desempeño de las funciones y una peor calidad da vida, un menor tiempo eutímico y una mayor probabilidad de tentativas de suicidio. Aunque los trastornos por abuso de sustancias mostraron una prevalencia alta en los pacientes con trastornos de ansiedad, la ansiedad comórbida parece ejercer un efecto independiente, perjudicial, sobre el funcionamiento, Incluyendo los antecedentes tentativas de suicidio (razón de probabilidad = 2,45, IC 95% = 1,4-4,2). Conclusiones: Se demostró una relación independiente entre la ansiedad comórbida y la mayor gravedad y el mayor deterioro de los pacientes con trastorno bipolar, lo que destaca la necesidad de un mejor tratamiento clínico de la ansiedad en esta población, en concrete, para mejorar la supervisión clínica de la tendencia al suicidio. También es importante determinar si un tratamiento eficaz de los síntomas de ansiedad puede disminuir la gravedad del trastorno bipolar, mejorar la respuesta terapéutica de los síntomas maníacos y depresivos y reducir las tentativas de suicidio.
